How Thor Infinity Reels plays
Every win adds a reel on the right. If that reel extends the win, another follows, and the chain runs until a reel adds nothing, with no fixed limit. The win multiplier starts at x1 and rises by one for every reel added.
- Thor: the wild, which helps to complete wins.
- Shields, helmets and axes: the higher-paying symbols, with J to A card royals below them.
- Mjolnir: Thor’s hammer, the scatter behind the bonus.
Long chains can also reach a fixed prize. Adding 12 reels to the starting three, which means reaching the 15th reel, pays the Infinity Bonus of 888x the bet on top of the win.
The Jackpot Respins
Six or more Mjolnir scatters in view when a spin sequence ends start the Jackpot Respins. The grid locks at the size it had reached, the hammers hold in place and three respins begin, with every new hammer also sticking and resetting the count to three.
Each hammer shows a cash value of 1x to 100x the bet, or one of four coloured jackpots: green pays 10x, blue 50x, red 250x and gold 2,000x. Fill a whole reel with hammers and another reel is added on the right, so the board keeps growing and the Infinity Bonus stays in reach. When the respins run out, every hammer pays its value.
So the base game feeds the bonus: the wider the reels had spread when the hammers landed, the more room the respins have to fill.
